API sets specific standards for lubricants, focusing on engine oils and other lubricants used in internal combustion engines. These standards classify oils into different performance levels (e.g., API SN for gasoline engines, API CK-4 for diesel engines). Manufacturers adhere to API standards for testing and certification, ensuring that lubricants meet industry performance requirements.

ISO addresses the classification, specifications, and compatibility of industrial lubricants through standards like ISO 6743. ISO viscosity grades (e.g., ISO VG 32, ISO VG 68) standardize lubricant viscosity for various applications. ISO standards guide testing procedures, ensuring lubricant quality and compatibility with equipment.

ASTM provides a comprehensive set of standards for lubricant testing, covering viscosity, wear, corrosion, and oxidation resistance. These standards also address compatibility between lubricants and various materials, aiding manufacturers in ensuring safe and effective use. Compliance with ASTM standards supports quality assurance in lubricant production.

EPA regulations focus on promoting environmentally friendly lubricants with low ecological impact. Guidelines emphasize biodegradability and toxicity considerations in lubricant formulations to minimize harm to the environment. EPA regulations on emissions and environmental impact indirectly influence the development and use of lubricants, ensuring compliance with stringent environmental standards.
